Err Pollution

As reported by ABC Australia, scientists in that country have found that water pollution may benefit marine invasive species. Specifically, certain invaders, including red bryozoans (lace corals), were shown to have evolved an increased tolerance for copper in the water. This is bad news when you consider that the main component of anti-fouling ship paint is copper, meaning that the use of a product meant to stop the spread of invasive species on ships may actually be selecting for pollution-resistance among those invaders. As if they need another avantage over native species!
